Our team is having a problem with Magento 2 layouts. Reading this link I gather that if we wish to re-enable a block that was removed in the blank theme, all we need to do is switch the referenceBlock to have an attribute remove="false" in our overrding XML file. However making that change is having no effect on the blocks being displayed on the frontend for us. The most that we can find is a Github post that is redirecting the original poster back here. Since he didn't post, my question is:
Is there anything else special beyond the documented XML changes that needs to be done to override a block removal in Magento 2?
Additional info (and stealthy subtle bump):
We are trying to override checkout_index_index.xml in a theme layout override.
No solution yet. When I get resolution I'll post, here and update the docs with a PR if it wasn't some minor thing missing on our end.
